Is this correct? Saw it online, am growing a 'Blushing Ballerina' brug

'Remove the leaves from the trunk of the plant, up until it creates the desirable Y. Leave those leaves intact, as this is where the plant will flower] Vegetative growth in brugmansia is described as the main trunk of the plant, before she makes the Y, or Fork.Brugmansia will create small leaves along this main trunk. Remove these leaves below the Y (or upcoming Y) and any shoots that might arise from the base to help the plant use all of it's energy into putting out that Y we mentioned above. I remove shoots, but not leaves, until she Y's. After it Y's, remove the leaves on trunk."'
